[OpenSIPS-Users] opensips and asterisk retransmits

[Bogdan-Andrei Iancu]

Hi,

Get a ngrep capture of the SIP traffic between * and OSIPS . Typically a 
retransmission is triggered by a lack of response from the other party, 
but to see what response is lacking, you need to see the ngrep capture 
of the SIP traffic.

Regards,
Bogdan
